What is a Barcode?

A barcode is a visual representation of data usually numbers or characters encoded in a machine-readable format. It helps automate product identification, tracking, and data management.

How Barcodes Work

Barcodes work by encoding data into a pattern of lines and spaces. When a Barcode Scanner or reader detects these patterns, it translates them into digital information, such as a product’s name, price, or serial number.

Accurate barcode data ensures efficiency in inventory management, shipping labels, and point of sale systems. It eliminates manual data entry errors and improves workflow automation.

Types of Barcodes

In today’s digital-driven world, barcode generators have become essential tools for businesses of all sizes. Whether you’re in inventory management, shipping, or retail, generating accurate barcodes can save time, reduce human error, and streamline data entry.

Code 128

Code 128 supports all ASCII characters, making it ideal for shipping labels, inventory tracking, and product packaging.

Code 39

Code 39 allows both numbers and capital letters. It’s often used for custom barcodes and asset labeling in logistics and manufacturing.

EAN-13

The EAN-13 barcode (European Article Number) is a 13-digit, industry-standard barcode used globally for retail products. It includes a check digit for validation.

EAN-8

A shorter version of EAN-13, EAN-8 is used for small items where space is limited.

UPC-A Codes

UPC-A barcodes are widely used in North America for retail items. They’re compatible with most barcode readers and point of sale systems.
